She is known for flaunting her ample bosom on the red carpet and has now shown she is just as sexy when she’s covered up.

Christina Hendricks looked stunning as she spoke at a Mad Men Q&A for the Screen Actors Guild Foundation Conversations Series in New York on Monday night.

The 40-year-old actress wore a demure, high-necked black dress which showed off her porcelain pins during the talk at the NYT Auditorium On Broadway.

The stunning star wore her red hair in loose waves over her shoulders and added a vintage feel to the look with a slick of crimson lipstick.

She paired the outfit with simple accessories consisting of a pair of pointed black stilettos and wore no jewellery except her wedding band and engagement ring from her husband of six years, Geoffrey Arend.

The Screen Actors Guild Foundation Conversations Series sees a host of the world’s leading acting talents host Q&As after screenings or undergo two-hour career retrospectives.

Christina appeared to chat with Mark Peikert, editor-in-chief of Backstage Magazine, about Mad Men, where she played Joan Holloway opposite Jon Hamm and January Jones.

The hit series, set in a 1960s advertising agency, had seven seasons after launching in 2007 before wrapping up in May this year.

Christina’s portrayal of Joan Holloway has earned her a huge six Emmy nominations, as well as four Screen Actors Guild Award nominations of which she won two prizes.

Other prestigious stars to speak at the Screen Actors Guild Foundation Conversations Series include Leonardo DiCaprio, Matt Damon, Ewan McGregor and Jennifer Aniston.

Despite the end of her Mad Men career, she has plenty to look forward to after wrapping up filming on 2016 horror The Neon Demon.
